RE: non-mandatory makefile include

[Rahul Jain]

Aha! I didn't realize that the -include was an actual Makefile directive,
not just a commandline option. Sorry for the confusion and thanks for
(unintentionally, I guess) clearing it up. :)

I don't have any rules to make this file: it's just a build environment
configuration file, but thanks for the suggestion.

And furthermore, you might want to make an optional non-mandatory include
to keep from building those include files if not really needed for the
current target, e.g.

  ifneq ($(MAKECMDGOALS),clean)
  -include $(deps)
  endif
